(County Rates as a Percentage of the U.S. Average)

Per capita income is a measure of the total personal income of an area divided by the resident population of the area. The percent of the U.S. average is computed by dividing the county per capita income by the national average and multiplying by 100. The map uses critical breaks such as the national average to organize the data into groups of common values.
